Magnetic resonance techniques have proven to be extremely useful in nearly every scientific discipline, from controlling spin dynamics in condensed matter physics to imaging diseased tissue in biomedical engineering.

Quantum Sciences Seminar Series - Yuimaru Kubo, CEA-Saclay – “Hybrid Quantum Circuit with a Superconducting Qubit and an Electron Spin Ensemble”
Wed, Dec 11, 2013, 12:30 pm to 1:30 pm

We report the experimental realization of a hybrid quantum circuit combining a superconducting qubit and an ensemble of electronic spins (Fig. a). The qubit, of the transmon type, is coherently coupled to the spin ensemble consisting of nitrogen-vacancy (NV) centers in a diamond crystal via a frequency-tunable superconducting resonator acting...

Quantum Sciences Seminar - Christopher Eichler, ETH Zurich - "Exploring quantum microwave radiation emitted from superconducting electronic circuits."
Tue, Dec 10, 2013, 1:00 pm to 2:00 pm

Superconducting electronic circuits have turned into one of the prime physical systems to investigate quantum optical and atomic physics phenomena in engineered solid state devices.

High Energy Theory Seminar - Liam McAllister, Cornell University - "The Wasteland of Random Supergravities"

High Energy Theory Seminar - Liam McAllister, Cornell University - "The Wasteland of Random Supergravities"
Mon, Dec 9, 2013, 2:30 pm to 3:30 pm
I will present results on the statistics of metastable vacua in string theory. Standard counts of string vacua, including the celebrated estimate of >10^500 flux vacua in type IIB string theory, do not incorporate the constraint of metastability, and therefore effectively count the combined number of maxima, minima, and unstable saddle points.

Condensed Matter Seminar, Waseem Bakr, "Synthetic condensed matter systems with ultracold atoms"

Condensed Matter Seminar, Waseem Bakr, "Synthetic condensed matter systems with ultracold atoms"
Mon, Dec 9, 2013, 1:15 pm to 2:30 pm
Recent advances in preparing, probing and manipulating ultracold atomic gases enable studying condensed matter physics in a very controlled setting. In the first part of my talk, I will describe quantum gas microscopy, a powerful tool for imaging and manipulating strongly interacting quantum gases containing thousands of atoms at the single atom...

High Energy Theory Seminar - Simone Giombi, Princeton University - "One loop tests of higher spin AdS/CFT"

Hamilton Colloquium Series - Emilia Morosan, Rice University: "Exotic superconductivity at the itinerant-to-local moment crossover"

Hamilton Colloquium Series - Emilia Morosan, Rice University: "Exotic superconductivity at the itinerant-to-local moment crossover"
Thu, Dec 5, 2013, 4:30 pm to 5:30 pm
The conventional wisdom that magnetism and superconductivity are immiscible has been losing ground for more than 25 years, in favor of the concept of magnetism-mediated superconductivity. Not only are magnetic interactions required for electron pairing in the famous Cu oxides and the Fe pnictides, but they seem to be the key ingredient for high...

Wed, Dec 4, 2013, 2:30 pm to 3:30 pm
"NEUTRINOLESS DOUBLE BETA DECAY SEARCHES WITH BACKGROUND-FREE DETECTORS" Neutrinoless double beta decay is a hypothesized nuclear transition whose observation would help resolve the puzzle of the nature of the neutrino (Dirac or Majorana fermion). In addition, it would provide a measurement of the neutrino mass.

Math Physics Seminar, Volker Bach, "On the Bogolubov-Hartree-Fock (BHF) Approximation for the Pauli-Fierz Model"

Math Physics Seminar, Volker Bach, "On the Bogolubov-Hartree-Fock (BHF) Approximation for the Pauli-Fierz Model"
Tue, Dec 3, 2013, 4:30 pm to 6:00 pm
The minimal energy of the nonrelativistic one-electron Pauli-Fierz model within the class of quasifree states is studied. It is shown that this minimum is unchanged if one restricts the variation to pure quasifree states, which simplifies the variational problem considerably.

High Energy Physics Seminar-Valentina Dutta-MIT-The Search for a Higgs boson Decaying to Tau Pairs with the CMS Detector

High Energy Physics Seminar-Valentina Dutta-MIT-The Search for a Higgs boson Decaying to Tau Pairs with the CMS Detector
Tue, Dec 3, 2013, 2:30 pm to 3:30 pm
The discovery of a new boson compatible with the expectations for the Standard Model Higgs propelled LHC physics into a new era. Studying the properties and couplings of the newly discovered particle immediately became a goal of primary importance.

High Energy Theory Seminar - Eva Silverstein, Stanford - "New solutions with accelerated expansion in string theory and applications"

High Energy Theory Seminar - Eva Silverstein, Stanford - "New solutions with accelerated expansion in string theory and applications"
Mon, Nov 25, 2013, 2:30 pm to 3:30 pm
We present concrete solutions with accelerated expansion in string theory, requiring a small, tractable list of stress energy sources. We explain how this construction (and others in progress) evades previous no go theorems for simple accelerating solutions.

Condensed Matter Seminar, Victor Galitski, "Topological Kondo Insulator"
Mon, Nov 25, 2013, 1:15 pm to 2:30 pm
In this talk I will review recent theoretical work on a new class of topological material systems - topological Kondo insulators, which appear as a result of interplay between strong correlations and spin-orbit interactions.

Special Condensed Matter Seminar, James Murray, "Superconductivity on the brink of spin-charge order in doped honeycomb bilayer"
Fri, Nov 22, 2013, 11:00 am to 12:00 pm
Using a controlled weak-coupling renormalization group approach, we establish the mechanism of unconventional superconductivity in the vicinity of spin or charge ordered excitonic states for the case of electrons on the Bernal stacked bilayer honeycomb lattice. With one
